I´m not to familiar with this carb & 1/2 set-up that is on this bike. I´m having a problem getting it started after it sets for while. Once it does start I have to keep it at about half choke in order for it to stay running. I have takin the bowl off to clean it out, but I´m a little spooked to do much more than that.Being it is as old as it is hate not to be able to find parts or anyone who can work on it if I were to mess something up. Has anyone else run into a similiar problem and if so could I ask what you may have done to resolve it? Any and all help would be greatly appreciated.
